Fig. 4

Control parameter, \({\alpha }_{m}\), dependence of toroidal to poloidal mean flow ratios. Circles represent the ratio of the mean toroidal to that of the mean poloidal flow magnitudes at \(r={r}_{2}\) under the tangentially magnetostrophic constraint, for \(\sigma =1\times {10}^{5} ~\mathrm{S}~{\mathrm{m}}^{-1}\), \(\sigma =1\times {10}^{6} ~\mathrm{S}~{\mathrm{m}}^{-1}\), and \(\sigma =1\times {10}^{7} ~\mathrm{S}~{\mathrm{m}}^{-1}\) at the epoch of 2010
